Featuring the same circuit board as the highly-praised GA-X38T-DQ6, Gigabyte's X48T-DQ6 could take overclocking capability one step farther through the X48 Express northbridge's higher-validated FSB stability.
Another thing everyone will notice is that the X48T-DQ6 uses a layout identical in nearly every way to the X48-DQ6, save for its use of DDR3 rather than DDR2 memory.
We could go on about its good slot layout that supports graphics cards coolers up to "triple thick" size, and even mention that the good overall layout is partly due to the fact that the GA-X48T-DQ6 supports only two PCI Express x16 graphics cards (with PCIe 2.0 mode available). Instead of repeating everything, though, we'll just point back to our description of GA-X48-DQ6.
The layout might be the same for the DDR2 and DDR3 models, but the X48T-DQ6 does have a slightly larger northbridge sink. Only Gigabyte knows why the larger sink wasn't used on the DDR2 model, as there appears to be enough space on both versions. The mounting pin locations are further apart on the wider sink, but Gigabyte updated the X48T-DQ6's mounting holes to support it, while leaving the X48-DQ6 with the same mounting pattern as its X38 Express equipped predecessor.

All the interfaces and third-party controllers are shared between the X48T-DQ6 and its DDR2 counterpart, and even the back panel ports are identical. Only the BIOS differs from the X48-DQ6 on the chart above, due to the different memory settings. Once again, we refer you back to the GA-X48-DQ6 for descriptions of each component.
